# Unreal Chemist vs MolViewApp

The clearest difference is rating: MolViewApp at 5.0 against Unreal Chemist's 4.5. MolViewApp also leads on in-app purchases (none vs 1) and ads (none vs shown). Unreal Chemist's advantage is ratings volume (68 vs 2) and iOS requirement (11.0 vs 15.0). On price and device support there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase. MolViewApp asks for nothing beyond the download.

MolViewApp holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Unreal Chemist has 68 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 73% of Unreal Chemist's written reviews are positive against 100% of MolViewApp's.

Unreal Chemist ships an update every 2 weeks, MolViewApp every 2 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
